Trading signal pipeline
A signal pipeline polls X for ticker mentions around the clock. On the official API, 429 errors hit exactly during volatility spikes, and two scraper vendors degraded above a few requests per second. On Sorsa, the flat 20 req/sec limit holds under load, so a red-day spike behaves like a quiet Sunday. The 429 retry code is still in the repo. It never fires anymore.
Giveaway verification platform
A solo-built giveaway platform verified follows, retweets, and comments through the official X API until the projected bill outgrew monthly revenue. The same checks now run on Sorsa's dedicated verification endpoints at flat per-request pricing. The migration took one weekend, mostly find-and-replace plus a new auth header, and unit economics flipped back to positive.
AI engineering team
An AI team waited months for official developer-account approval, then lost the account to an unexplained suspension. Sorsa needed only a signup and a key. The team pasted the Sorsa docs URL into Claude and asked it to port the existing client. The model got 90 percent of the way on the first pass, and the rest was renaming two fields.
